How Elite Rollover nights work

[JohnG]

Does anyone know how rollover nights for status work in the following situation? I have Platinum through my Ambassador membership. If I had 35 nights by the end of the year would:
a) I get 35 nights as I don’t need any nights for status (seems very optimistic)
b) I get 15 nights because that’s how many nights I have above the highest threshold, gold, I have passed
c) I get 0 nights as I haven’t exceeded the Platinum stay threshold (what I suspect)

Do IHG even do rollover nights? News to me!

c) is the answer

If you only had Gold now, the answer would be b).

Thanks Rob, was pretty sure that would be the case but wanted to make sure as it makes quite a big difference to how useful additional stays are for me.
